I have a UE32B6000 with the last official firmware from Samsung (named T-CHL5DEUC-2010.1_Step2). I don't know if I understand this guide correctly, but can I downgrade my TV to a previous firmware?

Because I update my TV using Samsung's firmwares, using T-CHL5DEUC_2009.0_Step1 first and after that T-CHL5DEUC_2010.1_Step2, but I didn't install any alternative firmware.

I don't want any alternative firmware or samygo, but I'm interested in downgrade my TV because I changed some values (without knowing what I'm doing) from service menu and now my TV sound is horrible (like metalic), and I read that if I change the firmware the values are reset and the sound problem dissapears.

Hi everyone! So, I have a UE40B6000VWXXH device with T-CHL5DEUC-2008.0 firmware, this is simple CI model. I successfully updated firmware to juuso's T-CHL5DEUC-2008.0-v0.24-GMT2-ArFIX2-ADFIX-fwver-net-auto but still no Content Library. The wiki for enabling wiselink movie is for CI+ models, for CI device I do have to "change the model number to B650 in the service menu"? Is there a description for this? (I found nothing in forum).

I did not wanted to blame you, juuso, I am really grateful for your help. Anyway, I cannot find 'Model' option under the 'Control' menu. There is a 'Model' under 'Option' with numbers like 'LB650' - but I don't want to mess with them. There are also things like 'Wiselink movie' under 'Sub Option' set to 'off'.

Men, I must say..... A big thank you to the author of this article. I was one of the unlucky ones that flashed new firmware without giving it any thought. Thinking newer is always better.... Not.... When I found out I could do more with my TV, but couldn't because I was on newest firmware I was disappointed. But when I found this article I was happy again. Carefully executed all the steps, and it worked like a charm I'm now back on T-CHL5DEUC.2008 with all benefits. Thanks agfain....
